Save and Sacrifice
A large part of the war propaganda effort, demanded sacrifice in terms of daily activities – saving left over waste fats for use in explosives, saving tin cans for metal to be recycled into military material, eating leftovers, recycling paper, growing vegetables and canning them for later home use, saving gasoline by driving cars slower and less often. The national speed limit was lowered to 35 mph! … All Americans needed to share in the burdens of shortages equally. Not to share in sacrifices for Victory was an unpatriotic act, and often was reported. (http://www.intheirwords.org)
Families collected scrap metal.
Even stars like Rita Hayworth lended their support!
